In addition to SPAL's top quality electric fans we also carry other accessories that you may need for a proper installation. A fan relay harness includes a thermostatic switch, relay, relay socket with ample wire, fuse and fuse holder, fan harness pigtail and 1/2" to 3/8" pipe bushing. The temperature switches are available separately as are the relay harnesses without the switch. A fan pigtail harness is usefull for a neat wiring installation. Fan mounting brackets allow endless mounting locations for your fan. A fan shroud gasket is available for the 16" fans to prevent the fan from damaging your radiator or condenser.
